Abstract

The effects of hydrogen charging on the γ(Ti-48Al-1V, at.%) and α2(Ti-25Al-10Nb-3V-1Mo, at.%) titanium aluminides have been investigated. Cracking at room temperature is associated with some form of lattice bond interaction or decomposition of strain-induced hydrides at the crack tip. The results of X-ray diffraction studies on Ti-48Al-1V at.% (Ti-48-1) are reported. The objective of the present study was to investigate the effects of hydrogen on the phase changes and hydride formation in these alloys. Hydrogen-induced cracking was found to occur as a result of hydrogen charging. The cracking appears after the formation of the hydride phase and is observed dispersed throughout the material.
